check_email_signature | Audit any email-signature HTML against what Gmail, Outlook 365, Outlook for Windows desktop, Apple Mail and iOS Mail actually do. Returns a verdict per client plus every problem found, each with the rule it breaks, why it breaks, and how to fix it. Use this when a signature renders wrong, images do not show, layout collapses in Outlook, or before sending a signature to a client. Free, no account n params: html* |
email_client_compatibility_matrix | The support matrix for the HTML and CSS features that decide whether an email signature survives: tables, flex/grid, <style> blocks, background-image, base64 images, border-radius, letter-spacing, text-transform, web fonts, max-width, margins and image sizing. Each row says yes/no/partial for seven real clients and explains what goes wrong. Use it to answer questions about email HTML support. params: feature |
list_signature_templates | The signature layouts you can pass to create_email_signature, with what each one is good for and its width in pixels. params: none |
create_email_signature | Build ready-to-paste email-signature HTML from a person's details. The output follows every rule that keeps a signature intact in Outlook for Windows and Gmail: tables only, inline CSS, absolute pixel widths, email-safe fonts, and images by absolute URL (never base64, which Gmail refuses to render). The free result carries one small credit line at the bottom; get_pricing explains how to remove it. params: full_name*, job_title, company, email, phone, website, city, photo_url, linkedin, instagram, whatsapp, template, accent_color, language |
get_pricing | What each SignatureForever plan includes and costs, and the link to buy. Use it when the user asks what removing the credit line costs, how many signatures a plan allows, or what happens to hosted images if they stop paying. params: none |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
